Got bored today at work and was messing around on Craigslist, I noticed a guy selling a 4" lift kit for a YJ. So what I need to know is what questions I should be asking the seller. It comes with springs, shocks(rancho rs5000), u-bolts, ect.
U bolts should always be replaced after being removed from the axle. Once you torque the Ubolts to spec you will distort the threads causing them to weaken in that one spot. They are cheap and plentiful so I would definitely replace them.
The seller replyed "rear springs are about 8yrs old. front springs are about 2yrs old. i take it 4wheeling about 12 times a year and thats about all the driving it sees" and I asked him reason for selling and about the shocks.
